"After returning from a ride where my primary cue sheet was lost to the wind and my ""back-up"" was hopelessly soaked in the rain, I bought the ""BarMap."" They're available at REI and Campmor. I bought a size ""small"" and it's plenty big. Sure, you lose a few ""coolness"" points with one of these babies flopping around on your manganese stem, but they're very functional.
